Abstract
In a free electron laser (FEL) oscillator, the optical pulse evolves through mode competition as a result of mirror losses, desynchronism, and amplification by the electron beam. The finite time for this evolution determines the optical response to an electron beam energy change. The ability of the FEL operating frequency to follow modulations in electron energy has been demonstrated experimentally [l-3] and theoretically [4]. Using a self-consistent FEL theory with dimensionless parameters [5], a longitudinal multimode simulation follows the evolution of the optical pulse over many passes of a FEL oscillator.
